I am sure that I don't have to spent much words on a band that is still on of my favourite bands of all time. Joy Division crossed my attention in the late 70's releasing their first singles and then their epoch-making first record that is on my record player for ages. This is this kind of music I won't miss for the rest of my life.
As far as I know this video of one of their classic songs was originally recorded during a Peel-session. Very rough and intense. You could see Ian suffer when he was singing the lyrics.
Another classic was filmed by Anton Corbijn as a dark and mystic video. He later paid tribute to them with his movie Control.
The video of Love will tear us apart is more tamed than the first ones I offered. Working with colours and turning them into negative was also a style used in the early 80's.
